General description and technical data for the DD-750 HY
The DD-750 HY is a universal, high-performance core drilling system with a 4-speed gearbox. It is
suitable for drilling holes within the range 52 mm – 750 mm dia. It can be powered either by the
D-LP15 hydraulic unit (fixed oil flow rate) or by the D-LP32 (with variable oil flow rate). The modular
concept permits angular drilling and the use of different baseplates employing different fastening
methods. The DD-750 HY can be operated with manual control of drilling feed pressure or with a
hydraulic feed unit. The D-R..L rails used by the drilling system can also be used with Hilti wallsaw
systems. Diamond core bits incorporating the Hilti DD-BU quick-change interface or with UNC
threaded connection ends can be fitted.

NOTE
The vibration emission level given in this information sheet has been measured in accordance
with a standardised test given in EN ISO 5349 and may be used to compare one tool with ano-
ther. It may be used for a preliminary assessment of exposure. The declared vibration emission
level represents the main applications of the tool. However if the tool is used for different appli-
cations, with different accessories or poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total working period. An estimation of the
